To aZLwhom it may concern:

Be it known that we, FRANKWV. SHELLEY and su est KIsER, citizensof the United States, residingTatAnderson, in the county of Madition' of the invention, such as will en able others skilled inifithe art to which it l appertains to make and usetheysame.

Our invention relates to improvements in that class of machines whichuse mud for forming bricks. 5

The objects and nature of our invention will morefully appear from the subj oined description and claims, reference being had to the accompanying drawings, in whichi Figure 1 represents a side elevation; Fig. 2,

a horizontalsectionon line g qy, Fig. 1; Fig. 3,

a'verticallongitudinal section; Fig. 4, a detail in perspective, showing theparts upon the under side of the reciprocating plunger;

1 l V Fig. 5, an enlarged view of part ofthe niachine, showing the removable plates; Fig. 6,. a section of the mud-box and plunger, and Fig. 7 the plunger with adjustable side plates.

A represents the mixing-drum, which is preferably made of iron,having spaces or openings (1. and a for the spout and rectangular box A. The drum is supported from a truck, A, by legs A. This truck is provided with cross-beams a and a pivoted extension,

Afiwhich' ordinarily is in alhorizontal posi tion, but may be turned vertically. \Vithin thedru'm is anagitator or mixer,- A, formed of shaft A,-journaled in the drum in any suitable manner, and arms a and a". The arms a are broader than the arms ar, and are used toscrape the material from the bottom B of the drum into the mud-box, which is connected with said drum byan opening, a, in the bot tom of the latter. 1 This opening a is continul ous with the o enin a and is closed b a rect- P a: a y

angular or' nearlyrectangular box, A, which is attached to the drum. This box maybe curvedat its topfto permit of its being attached directly to thecylindrical drum, and

its lower part made rectangular, to form, with opening a a rectangular opening, so that the mud will fall evenly into the mud-box, so that each of the molds will receive its proper pro= portion of mud.

Attached tothe bottom of the drum in any suitable manner is a mud-box, B, which, as before stated, communicates with the interior of the drum by means of opening a. It is open at its rearrend for the admission of a hori zontal reciprocating plunger, 0, which forces the mud toward the front of the box. The rectangular box A closes that part of the box whichextends laterally beyond the walls of the drum, and a plate, 0', closesthe forward extension, 13. In the bottom of this extension is the dieB having openings b for themudto escape into the molds B, placedupon the truck. The'forward end of the die is provided with a lip, b which closes the space between the die 13 and the front wall, I), of extension B. The wall I) is'preferably provided with-an inward projection, 21*, in contact with the lip b, which may be curved, as shown. The die B is pivoted at its rear end to the box 13, so that when a stone or other hard object too large to pass into the molds makes its exit through the openings b the forward end of the die will'bc lifted and the object carried out with the mold; The lip b prevents the mud in the box passing out at the front end when the die turned to its place.

Within the box B is a plunger, 0, which forces the mud in the box through the open ings in the die, and is provided with a plate, a, which closes the opening a when the end 0 abuts against the extension 13. The sides of the plunger are provided with removable plates c, held in place by set-screws c, whichpermit of the plates being adjusted to take up the wear caused by its reciprocating movement. The sides of the box Bare also provided with recesses for the removable plates I), held in place by set screws b by which the plates can be adjusted toward the plunger to take up the wear. The plates 0' and b in addition to taking up the wear, prevent leakage of mud from the box. plates 0 and b become too much worn, they can readily be removed and new plates substituted therefor. In the under side of plate 6 is formed a dovetail groove, 0, in which 'is IOO placed a dovetail slide, 0", having a pin, 0", to which a pitman, O, is attached,'for the purpose of reciprocating the plunger 0.

To regulate the stroke of the pitman, I provide a stepped plate, 0", which is held in place by ways 0 on the plunger, and is reciprocated by means of link and lever O. desired to send the plunger forward with greater velocity or force, the step nearest the dovetail slide is forced opposite the dovetail groove 0, so that the dovetail slide will strike it in its forward movement. The extent of the stroke can be regulated by using the different steps. The pitman O is attached to a crank, d, on a vertical shaft, D, which is j ournaled on the drum, and connected by gear d d" to the shaft A, which imparts its motion to the shaft D. Upon this shaft is a wiper, d, which moves the carriage E forward at each revolution of the shaft by wiping a stationary and upward extension, 6, of the carriage. The wiper may be provided with .a roller, which reduces the wear upon said carriage. This carriageis formed of a frame having all-its parts fixed, and provided with a recess, e, for the shaft D, and forms a stop for the return movement of the carriage. This movement is accomplished by means of a leyer, E, pivoted to a standard, 0}, attached to r he tru k- Iivoted to one arm of the lever E is alink, E, which extends to and is pivoted upon the stationary center piece, 6", ,of the carriage E. The opposite end of the lever is curved in such manner as to be in line with the wiper 1 which, after forcing the carriage forward, strikes the free arm of the lever, and causes the opposite end to draw the link, and consequentlythe carriage, back into position ready for the wiper to move it forward again.

The operation of the machine is as follows: Mud is placed in the drum and stirred by the agitator to break up the lumps. The motion of the agitator is imparted to theshaft D, gear 01 and d", which reciprocate the plunger. The hand nearest the bottom of the drum is forced by scrapers a through the opening a into the mud-box, and plunger B, as it moves forward, forces the mud out of the extension into the molds, and at the same time cuts off the supply from the drum by means of plate a. The molds are placed beneath the mud-box, and are forced forward beneath the extension by the carriage E, which returns at a faster rate than it moves forward, to permit the operator to place the molds beneath the mud-box as fast as they are taken out from the front of the ma chine. The molds followeach other .so rapidly that the mud does not fall between them, and mud in the mold forced out by the carriage is leveled by the die, which is weighty enough to serve this purpose.

are aware that shafts provided with a wiper having a roller thereon are old, and thatcarriages have been moved by such a wiper; but we are not aware of a recipro- WVhen it is eating carriage having a projection upon its top, combined with a lever mounted upon a standard, one end of said lever connected to said carriage by a link, and a revolving shaft having an arm which alternately strikes the projection and the free end of the lever.
